There was an article posted here about two years ago, with about 50 authors, confirming two earthlike planets from the Kepler mission. Does anyone know the title of that article? I can no longer find it.
http://www.sciencemag.org/content/340/6132/587.abstract or http://arxiv.org/abs/1304.7387 That's only 1 year old, but it has the author list.
Note : There is the Extrasolar Planets Encyclopaedia, which has an exhaustive bibliography - http://exoplanet.eu/ - and is actually fun to peruse, if you are interested in exoplanets.
I don't know that particular article. The two mentioned in the first comment and the two in the third were discovered in common missions so it would make sense for them to be presented in the same article.
Here is a nice uptodate overview of habitable exoplanets from Kepler Missions. I'm assuming the article would have been about two of these planets.
